  However, in this container, when the stopper tube is pulled out and then returned to the inside again, the inside of the measuring chamber is always in communication with the outside. It was difficult and there was a risk of over-pouring.

    Therefore, the present invention is easy to use and impairs the airtightness of the contents by mounting a spring between the support member attached to the mouth and neck of the container body and the measuring chamber that moves up and down with respect to the support member. An object of the present invention is to provide a quantitative application container that can be easily assembled.

The first means is
A container body 2 that stands up the mouth and neck 8, and
A support member 14 in which an inward flange-like top wall 20 is continuously provided from the upper part of the fixed cylinder 16 attached to the outer surface of the mouth-and-neck part 8, and the connecting cylinder 24 is erected from the upper surface of the top wall;
An elevating cylinder 42 that is provided with an outward flange-like bottom wall 46 on the outer surface of the intermediate part, and that can be raised and lowered and liquid-tightly fitted to the connecting cylinder 24 of the support member 14,
A pour-out which forms a measuring chamber 58 together with the elevating cylinder 42 by connecting the lower edge of an upper small-diameter peripheral wall 52 having a nozzle-like opening 56 at the upper end to the outer edge of the outward flange-like bottom wall 46 Cap 50,
A sealing cap 76 covering the outer surface of the weighing chamber 58;
Between the opening 56 of the pouring cap 50 and the outward flange-like bottom wall 46 of the elevating cylinder 42, a pressing protrusion 66 passing through the opening 56, a skirt 68 below the pressing protrusion 66, and the pouring A pouring valve member 64 having a spring material 70 biased upward toward the upper lower surface of the cap 50 is provided, and the pouring valve 72 for opening and closing the opening is formed by the pouring valve member 64 , and the raising and lowering In the quantitative application container formed with the inflow valve 60 that opens and closes by its elevation in the cylinder 42,
An elastic member 84 is interposed between the upper surface of the inward flange-like top wall 20 outside the connecting cylinder 24 and the lower surface of the outward-flange-like bottom wall 46, and
The sealing cap 76 is formed so as to be able to push down the lifting cylinder 42 through the dispensing cap 50, and is attached to the container body 2 side so as to be able to hold the pushed-down state.
Further, the elastic force of the elastic member 84 is set to be larger than the elastic force of the spring material 70.

  This means adopts an elastic member such as a spring as a means for raising and lowering the measuring chamber, and when the cap is removed, the measuring chamber is automatically raised by the elastic force and the inflow valve is closed. It is. However, it is a problem how much the elastic force of the elastic member is set. If the elastic force is too small, when the cap is removed and the pressing protrusion is pressed against the scalp, the pressing protrusion is There is a possibility that the elastic member is compressed instead of the spring material to be biased and the outflow valve is opened.

    The “support member” is for supporting the weighing chamber so as to be movable up and down, and has a connecting cylinder into which a below-described lifting cylinder main body can be moved up and down and is fluid-tightly fitted. Further, an elastic member storage space is provided between the outer surface of the connecting tube and the inner surface of a leg tube described later.

    The “elevating cylinder” has an outward flange-like bottom wall that is the bottom wall of the measuring chamber connected to at least the intermediate part outer surface of the straight cylindrical elevating cylinder main body. A cylinder wall (inner cylinder part) suspended from the outer edge of the wall is slidably fitted to the outer surface of the fixed cylinder of the support member.

  The “pour-out cap” has a peripheral wall having a lower end connected to the outer peripheral portion of the outward flange-like bottom wall of the lifting cylinder, and the upper portion of the peripheral wall is bent upward and inward, and is preferably a substantially bell with an upper end opening. It is formed into a shape.

  The “weighing chamber” is formed of an elevating cylinder and a dispensing cap, and the upper and lower positions are set by fitting the elevating cylinder main body liquid-tightly and slidably in the vertical direction. It is formed to be movable up and down.

  The “elastic member” is interposed between the support member and the measuring chamber to urge the measuring chamber upward. The elastic force of the elastic member is set to be larger than at least the elastic force of the spring member for urging the pressing protrusion upward when the measuring chamber is at the upper limit position. Furthermore, in order to prevent liquid leakage from the connecting cylinder, the connecting cylinder and the elevating cylinder main body need to be relatively tightly fitted, so that an elastic force large enough to overcome the resistance force of both of them is provided. Necessary. The elastic member may be made of synthetic resin, but is preferably made of metal because of its large elasticity. However, in this case, it is necessary to set the liquid tightness of the connecting cylinder and the lifting cylinder body to be particularly high so that the content liquid does not come into contact with the metal elastic member.

  The “sealing cap” covers the outer surface of the measuring chamber in a liquid-tight and air-tight manner. The sealing cap can be attached directly or indirectly to the container body. For example, the lower portion of the sealing cap may be fitted to the upper end portion of the body portion of the container body, or may be fitted to the outer surface of a guide cylinder described later of the support member and attached to the container body via the support member. The hermetic cap can be formed of a cylindrical outer lid and an inner lid that is built in the outer lid and shaped along the shape excluding the opening of the measuring chamber.

  The second means includes the first means, and the leg cylinder 48 is suspended from the outer peripheral side of the bottom of the measuring chamber 58 to the outer surface of the fixed cylinder 16, and both the leg cylinder 48 and the fixed cylinder 16 are opposed to each other. An engagement recess 92 for restricting the upper limit position and lower limit position of the weighing chamber 58 is formed on one of the surfaces, and an engagement protrusion 94 inserted into the engagement recess 92 so as to be movable up and down is formed on the other side. The engaging protrusion 94 is provided between the facing flange-like bottom wall 46 and the inward-flange-like top wall 20 so as to be locked in the engaging recess 92 in a state where the elastic member 84 is elastically compressed. .

  In this means, in order to restrict the upper limit position and the lower limit position of the measuring chamber, in other words, in order to restrict the range in which the elastic member extends, an engaging recess and an engaging protrusion are provided. The elastic member is configured not to be compressed when the spring member is compressed by pressing the locking protrusion against the scalp while the measuring chamber is in the upper limit position.

  The “engaging recess” has a vertical width opposite to the vertical width of the measuring chamber and is formed on the peripheral surface of the leg cylinder or the fixed cylinder.

  The third means includes the first means, and connects the guide cylinder 18 surrounding the fixed cylinder to the outer surface of the fixed cylinder 16 via the connecting piece 9 and fixes the guide cylinder 18 Extending above the cylinder 16 and suspending the leg cylinder 48 from the outer peripheral side of the bottom of the measuring chamber 58 to the inner surface side of the extension cylinder part, on one of the opposing surfaces of the leg cylinder 48 and the guide cylinder 18, An engaging recess 92 for restricting the upper limit position and the lower limit position of the measuring chamber 58 and an engaging protrusion 94 inserted into the engaging recess 92 so as to be movable up and down are formed on the other side. 46 and the inward flange-like top wall 20 are provided so that the engaging protrusion 94 is locked in the engaging recess 92 in a state where the elastic member 84 is elastically compressed, and the outer surface of the guide tube 18 A sealing cap 76 is fitted to the.

  In this means, a guide tube for guiding the leg tube on the weighing chamber side is provided around the fixed tube, and between the leg tube and the guide tube, an engagement recess and an engagement protrusion similar to the second means are provided. In addition, a sealing cap is fitted (preferably screwed) to the outer surface of the guide tube in order to improve the sealing performance of the measuring chamber.

  In the second means or the third means, the “outer peripheral part of the bottom of the measuring chamber” means either one or both of the outer peripheral part of the bottom wall of the measuring chamber and the lower end of the dispensing cap. To do. As will be described later, the leg tube can be formed in a double cylinder shape with each cylindrical wall hanging from both the outer peripheral portion of the bottom wall of the measuring chamber and the lower end portion of the pouring cap. It is also possible to form a single cylindrical wall that hangs down from only one of the outer peripheral portion and the lower end of the dispensing cap.

  Further, in the second means or the third means, the engaging recess 92 can be formed on any one of the peripheral surfaces of the leg tube 48 and the fixed tube 16 or the guide tube 18, and It can also be formed on a part of the circumferential surface in the circumferential direction.

The invention according to the first means has the following effects.
○ Since the sealing cap 76 is removed, the measuring chamber 58 is raised, and the pressing projection 66 is pushed in, so that it can be used.
○ With the sealing cap 76 removed, the elastic force of the elastic member 84 is greater than the elastic force of the spring material 70, so when pressing the pressing protrusion 66 against the scalp, only this pressing protrusion 66 is measured. The dispensing valve 72 can be reliably opened and closed by retreating into the chamber 58.

  According to the second and third aspects of the invention, the elastic member 84 is compressed by the pressing force when the pressing protrusion 66 is pressed against the scalp at the upper limit position of the measuring chamber 58. In addition, only the pressing protrusion 66 can be reliably pushed inward.

    Furthermore, according to the invention relating to the third means, since the sealing cap 76 is provided on the outer surface of the guide cylinder 18 so as to be fitted, the sealing performance can be improved.

An inflow valve 60 that opens and closes by raising and lowering the measuring chamber 58 is formed on the inner surface of the upper end portion of the elevating cylinder body 44 by bringing the flange 30 of the communication cylinder 22 into contact with the liquid tight. The inflow valve 60 can also be formed by bringing the upper end of the lifting cylinder body 44 into liquid-tight contact with the lower surface of the flange 30.

  The dispensing valve member 64 has a frustoconical shape with a plurality of communication holes formed vertically through a skirt 68 inclined obliquely downward from the lower end portion of the cylindrical pressing protrusion 66 inserted through the opening 56. The spring material 70 provided is projected, and the lower end portion of the spring material is brought into contact with the upper surface of the outward flange-like bottom wall 46 so that the upper surface of the skirt 68 is the inner peripheral portion of the peripheral wall 52 of the dispensing cap 50. The lower surface is urged upward to come into contact therewith, and the pouring valve 72 is formed by these both surfaces. The pressing protrusion 66 protrudes from the opening 56 at the upper half, and a plurality of extraction grooves are provided vertically on the outer surface of the upper half of the pressing protrusion 66.

  The hermetic cap 76 is composed of a cylindrical outer lid 78 and an inner lid 80 built in the outer lid. The outer lid 78 has an engagement rib 82 attached to the inner surface of the lower end of the cylindrical wall fitted in the engagement recess 10. Further, the inner lid 80 extends from the lower end of the top small cup body that houses the pressing protrusion 66 along the outer surfaces of the peripheral wall 52 of the pouring cap 50 and the upper half portion of the leg tube outer cylinder portion 48b. The outer surface is hermetically covered, and the lower end portion is in contact with the lower inner surface of the outer lid 78 away from the lower half portion of the outer cylinder portion 48b.

  In the present invention, a spring is formed between the upper surface of the inwardly flanged top wall 20 and the lower surface of the outwardly flanged bottom wall 46 in the gap between the connecting cylinder 24 and the fixed cylinder extension cylinder wall portion 17. An elastic member 84 is interposed. The elastic member 84 has an elastic force capable of overcoming the frictional force between the connecting cylinder 24 and the lifting cylinder main body 44 and pushing up the measuring chamber 58, and the elastic force is the elastic force of the spring material 70. Set to be larger than In the illustrated example, an inward stepped portion 86 connected to the inner cylindrical portion 48a from the outer peripheral portion of the bottom wall of the measuring chamber is formed, and the upper end portion of the elastic member 84 is locked to the inward stepped portion 86.
